2.  LED display system is aimed at the colleges and universities for displaying day-to-day information
continuously or at regular intervals during the working hours.
 Being GSM based system, it offers flexibility to display flash news or announcements faster than the
programmable system.
 The LED display system mainly consists of a receiver and a display board which can be programmed
from an Arduino.
 It receives the message through serial port and display the desired information after necessary code
conversion.
 It can serve as an electronic notice board and display the important notices without any delay thus
avoiding the latency.
 The LED display is easy to expand and it allows the user to add more displays at any time and at any
location depending on the requirement.
 Keywords: P10 LED Display, Arduino, Andriod Phone, Bluetooth HC05, GSM module.
ABSTRACT

3.  Now-a-days LED message scrolling displays are very popular. These displays are used in shopping malls,
theaters, schools, traffic signs, public transportation etc.
 The problem of this display is to carry a computer or for generating and sending message to LED moving
display board is big problem and it can also increase the cost.
 To make the LED display more portable, a GSM mobile phone is used instead of computer for generating
message to LED display.
 A text message is typed in the GSM mobile and send it by using SMS service of the mobile to LED display.
 A arduino board is connected to LED display is used to receive the message and send it to the controller
circuit of the LED display.
 Then controller circuit of LED display is display the text message .By using arduino it is possible to change
the message in the LED display from anywhere in the world. It can be reduces the cost .
 The project uses a arduino board at the display side with Atmel 328P microcontroller to send text to drive
the LED display board. Along with these a power supply unit and supporting hardware for microcontroller
is used.
INTRODUCTION

4.  The main objective of the project using GSM module we can send message to any distant
location and to develop a wireless notice board that display notice in the form of text.
 Consume less power and easy to operate also notification can be delivered in within second.
The voice calling feature can be added with the proposed system as a further enhancement
for using the system.
OBJECTIVE

5. Electronic Notice Board with Multiple Output Display
prof. Kruthika Simha Shreya Chethan Kumar, Parinitha C, Shashidhar Tantry (Department of Electronics
and Communication Enggineering, PES Institute Of Technology, Banglore College of Engineering
Belagavi, India) In this paper simha, it can be easily integrated with general purpose display board to
provide its mobility. The system acept the message from of SMS and display on the notice board.
Development of Simple and Low Cost Android Based Wireless
Notice Board Neeraj Khera, Divya Shukla, Shambhavi Awasthi In this paper the technological
advancement of the notice board is purposed that will help to save time and resources. Also it makes
the information available fast to the person.
Bluetooth based Smart Home and Digital Notice Board
This paper is based on home controlling application and notice displaying using android has been built.
This project is based on the LCD display and LPC2148 Microcontroller.
LITERATURE REVIEW

6. BLOCK DIAGRAM

7. Power Supply:-
 It requires 5 Volts 10 Amp current. Power supply is an step down transformer. For getting +5 Volts supply
we are using SMPS.
SMPS:
 SMPS stands for Switched Mode Power Supply. The input to SMPS is 230 Volts ac and output is +5 Volts. A
Switched mode power supply is an electronic power supply that incorporates a switching regulator to
convert electrical power efficiently.
HARDWARE DETAILS

8. P10 LED Display:-
 This large, bright 512 LED matrix panel has on board controller circuitry designed to
make it easy to use straight from your board. Clocks, Status displays , graphic
readouts and all kind of impressive display project are easy to create using this
display. The distance between two points are 10mm then it is called as P10 LED
display. P stands for namely pixel and pixel stands for dot.
 It displays 16 rows and 32 columns total 512 led shown in one led display. P10 led
display contain shift register ICs and data transfer serial in parallel out. It is tough
frame material. the Arduino Uno and Arduino Nano models.

9. HC-05 embedded Bluetooth serial communication module has two work modes: order-response work
mode and automatic connection work mode. And there are three work roles (Master, Slave and
Loopback) at the automatic connection work mode.
When the module is at the automatic connection work mode, it will follow the default way set lastly to
transmit the data automatically.
When the module is at the order-response work mode, user can send the AT command to the module to
set the control parameters and sent control order.
Bluetooth HC05

10. It will show on your DMD display board and scrolled automatically. If you have any doubt or
problem then feel free to ask in comment below else if it works perfectly give REP to this post.
ARDUINO

11. The logic level convertor is also called as level shifter, level
translator. Level convertor is a small device that safely steps
down 5 Volt signals to 3.3 Volt and step up 3.3 Volt signals to 5
Volt.
LEVEL CONVERTOR

12. The proposed system “IOT Based Digital Notice Board” is
cheap, quick reliable and secured for any organization that
requires to circulate notice regularly and reduce physical efforts.
We are using GSM technology so there is no problem of the
range i.e. distance. We can send notice from any location. The
proposed system uses SIM900, LED Display, GSM module,
ATMega328. It has proposed its advantage in advertisement.
